Alpine has put its formidable engineering skills to work in creating the CDA-118M marine CD receiver. This stereo not only delivers top-notch sound, but its bullet-proof construction allows it to handle the toughest marine applications.

Built to take it
Alpine hasn't just beefed up a regular car stereo for marine use with the CDA-118M. The receiver is fully waterproof, measured against rigorous industry standards, and is certified as resistant to salt fog and UV exposure. Strict marine testing, including exposure to jets of water and salt-chamber exposure, ensures it'll hold up to life on the water. The large 3.6" tall face looks great in your boat, while the chassis behind the face is a direct fit or replacement for many standard marine stereos.

Make your iPod part of the crew
The included KCU-440i iPod® cable provides an audio connection and charging for your player, while the large double-action encoder knob makes it easy to dial up the songs you're looking for. You'll also find a built-in USB input ready for your thumb drives and two auxiliary inputs for other audio sources.

Excellent audio performance
Its strong internal amp delivers powerful output, and you can shape the sound with the 2-band parametric equalizer. The stereo also features a high-pass filter that'll keep your full-range speakers clear by eliminating the extreme low bass that they can't handle, plus a low-pass filter for your subwoofer.

The CDA-118M offers three sets of preamp outputs for connecting an amplified system. Use Alpine's optional IMPRINT sound tuning processor to turn your vessel into the perfect listening space  it measures the acoustics in your listening area and adjusts the stereo's settings automatically to create a perfect audio environment.

Great head unit

Great head unit. I shouldn't have waited so long to switch. My sony head unit would cut out at higher volumes. Also, the dual zone on this is perfect for tower speakers. Having the ability to keep the speakers in the cabin at a lower level is an awesome feature

Tremendous Head Unit - Marine or Otherwise

Written By moosehead, Denver, CO on Monday, May 21, 2012

Beautiful head unit with sturdy marine construction, great sound, and phoenomenal control features. Multiple source input options including very well executed Ipod Controller on main wheel with corresponding menu/screen read out. Superb sound, solid function even in rough and wet marine environment, has never faltered. Remote works well. Another superb Alpine unit, I would even put this in a automobile it is so well executed.

Awesome stereo

Today I installed the following into my 2008 Glastron GT225 ski boat:
1. Alpine CDA-118M Marine Receiver
2. Alpine KCA-SC100 SiriusConnect to Ai-Net Interface
3. Sirius SC-VDOC1 SiriusConnect Plug and Play Dock
4. Sirius Stratus 6
The system is working perfectly from the very first power up.
Made one call to Crutchfield tech support and that was answered instantly (the box for the SiriusConnect Plug and Play Dock and the Crutchfield website do not list the Stratus 6 as compatible, but it certainly is).
Also, one major correction is needed to the Crutchfield product overview: the CDA-118M slides into a standard DIN !!! (The product overview states a 3.6 inch tall chassis. That is not true. The entire chassis behind the large faceplate is normal DIN size. A side photo that shows the chassis would be very helpful.
Since Crutchfield does not supply adapter harnesses yet for the marine industry, you will have to transfer the connector from your old pigtail and crimp it onto the pigtail on the CDA-118M. Not a big deal. It would be great if Crutchfield offered such a universal connector to marine customers. Therefore I will wait til next year to replace the speaker wire, if ever.

[Editor's Note: Thanks for bringing this to our attention. We have updated our database.]

Marine Rated

Marine Receiver: The
Alpine CDA-118M marine CD receiver is designed for full operation in your boat.
The CDA-118M comes in a 1.8 DIN faceplate size, for an easy upgrade for standard
marine head units. This unit features a large 2-line LCD screen which is even
viewable in direct sunlight. Its skip-resistant CD mechanism ensures continuous
playback while you are out on the water. The CDA-118M is fully IPx5 waterproof
and salt fog/UV certified. EEPROM no-loss memory, ensures even when the boat is
not in use and the battery is disconnected, all your radio presets, zone
controls, sound adjustments will stay intact.

Marine Certified: The CDA-118M undergoes strict marine testing, including
intrusion protection and salt fog tests to ensure performance on water
conditions. Testing includes being subjected to a jetting water stream at 3.3
gallons per minute, and the unit must stay water-tight for 3 minutes at a
distance of 10 feet. For salt/fog testing, the unit is placed in a chamber to
withstand water with %5 sodium chloride (salt), sprayed at a rate of 12ml/hour
for 24 hours. The CDA-118M is IPx5 rated and ASTM-B117 certified

Note: This unit is specifically designed for marine applications.
However, it is not waterproof and should not be installed in a location
where it can get wet.

Caution on Connected Devices: Note that optional products such as the
compatible CD-changer, SAT receiver, HD Radio, Bluetooth module, Imprint audio
processor, or Power Pack have not been designed for marine use. Extra care must
be taken during installation to protect these products from the marine
environment.

Display Features

1.8 DIN Faceplate: The CDA-118M comes in a 1.8 DIN faceplate
size, for an easy upgrade for standard marine head units. The CDA-118M requires
a rectangular cutout in the bulkhead for inserting the chassis. Six screws
(supplied) fasten the faceplate against the mounting surface, and hold the
waterproof gasket against the bulkhead. A template is supplied to assist you
with the cutout and drilling the screw holes.

Note: The receiver does not include a mounting sleeve or
ISO-mount screw holes to accommodate standard I-, J-, or E-sized automotive
installation.

Fold-Down Face: The unit features fold-down face to further protect the CD mechanism. The face must be

CDA-118M marine CD receiver features a Zone 2 stereo RCA output which allows you
to output the same source to a second location on your boat with independent
volume control.

High Pass Filter (HPF): The speaker level and front line
level outputs have a selectable crossover (HPF); off (default), 60Hz, 80Hz, or
